Upper line

Microsoft has said a fix has been implemented to restore email and calendar services to thousands of users who reported outages early Monday morning, but when exactly the programs will come back online remains unclear.

Key facts

More than 2,100 people had reported problems with Microsoft 365 on the site Down detector from 10:30 a.m. EST Monday, with 86% of reports coming from issues with Outlook, 9% with Exchange, and 6% with Sharepoint.

A post to the Microsoft 365 account on X, formerly known as Twitter, said most users had problems accessing Exchange Online – a cloud-based email server – and Microsoft Teams calendars.

Microsoft said it had started implementing a fix from 9 a.m. — shortly after reports of problems began to increase significantly — which includes “manual reboots on a subset of machines that are in an unhealthy state,” but did not provide an estimated time for full recovery.

The company added that a “recent change” was likely responsible for the outage, and that the change has been reverted.

Although Microsoft did not specify which change affected programs, Monday morning was as well rollout of a new Recall AI tool for Windows Insiders designed to take regular snapshots of computing activity—essentially a “photographic memory” for computers—to store on PCs and make searchable later without remembering exact keywords or dates.

The feature first debuted in May, but its initial version was criticized for privacy and security issues, leading to the full launch being delayed.
